In the above step, you have created enough space so that Ubuntu can be installed on your system. Therefore, in this step, you are required to install the Ubuntu ISO Image based on the system building.
Once it is downloaded, you can burn the Ubuntu ISO image to DVD. Alternatively, you can make a bootable USB stick. This can be done using the Universal USB Installer or Rufus. Make sure there are BIOS and UEFI compatible respectively.
Thereafter, you can follow the instructions mentioned below:
- Insert the DVD or USB stick in the drive.
- Then, reboot your machine.
- Use function keys to guide UEFI or BIOS to boot up from USB or DVD. In this step, F2, F10, or F12 keys can be used based on the specifications.
When you boot-up by the media, you will see a new screen (Ubuntu Boot Screen). Here, you can do the following:
- Select the “Install Ubuntu” option from the menu,
- Press “Enter” in order to continue.
Once the bootup process completes, you will see Ubuntu running on your system. Now, you can do the following in order to launch Ubuntu successfully on your system.
- Click on the (2nd) icon located on the top and select the “Install Ubuntu”.
- Thereafter, choose your language for installation.
- Click “Continue”.

- Pick the installation type. At this point, you can select “Install Ubuntu alongside Windows 10”. This option takes care of the partition.
Note: The recent steps can be followed when you do not prefer a custom partition. In case, you wish to go with a personalized partition then you can click on the Something else option and click Continue.
Caution: Do not select the Erase disk and install Ubuntu option as this will wipe out the disk in seconds.
Now you are done installing and launching Ubuntu on your system. Next to this, we will create personalized partitions.
Step 4: Create Custom Partitions
To learn how to dual boot Windows 10 and Ubuntu, you will have to create partitions. If you prefer to create custom partitions then you can go through the following discussion. Here, you can create two types of partitions; root and home (also swap if needed).
Quick Note: If you use a fast SSD or have very limited RAM resources then you can create a swap partition.
To create a root partition, you will have to choose the shrinking space that we created earlier. Then, click on the (+) icon located below. When you see the partition settings, you can apply the following settings:
- Type for the new partition- Primary
- Size- 20000 MB at least
- Use as- EXT4 journaling file system
- Location for the new partition- Beginning
- Mount point- /
After configuring the partition, you can click on the OK button.
To create the second partition which is home, you can perform the steps as specified above. However, the size and mount point would be different this time. Go through the following steps to understand better:
- Type for the new partition- Primary

How to Perform Dual Boot Ubuntu on Mac?
The process of dual boot Ubuntu on Mac is not that easy. For some users, it is quite hard to install Ubuntu on your macOS.
If you install Ubuntu on Mac, a few hardware functionalities may not work properly. It can include a Touch Bar, USB-C, and others.
Caution: We suggest you install Ubuntu only when you are aware of the technical practice so that you can repair your PC if something goes wrong in between.
Yet you require Ubuntu to be installed on your macOS then we are bringing you some easy to go steps. Following these steps, you can initiate the dual boot process with Ubuntu and macOS. So let’s get started!
Step 1: Take a Backup
Before making any huge changes to your PC, it is recommended that you create a backup of your important files and documents. This is because if something does not happen as expected, you can at least create a partition of the boot drive and restore macOS.
Step 2: Install Ubuntu
In this step, you are required to download Ubuntu on your system. This can be done from Ubuntu’s official website. Also, make sure that the version you are installing of Ubuntu should be compatible with your Mac computer.
Step 3: Create Ubuntu Installation Drive
To create an installation drive, you can use a USB drive. The drive should have a capacity of 2 GB. Before you create an Ubuntu installation media, you need to format the USB to make sure it is empty.
Format the USB Drive
If you want to know how to format the drive then you can go through the following instructions:
- Go to the “Disk Utility”.
- Choose the “USB drive” from the left sidebar.
- Click on the “Erase” button located on the top of the menu bar.
- Now in the “Format” field, it should be “MS-DOS (FAT).
- In the “Scheme” field, select the “GUID Partition Map” from the drop-down.
This should format your drive. In case the Disk Utility does not allow you to have this format then you can try this same thing with diskutil and Terminal.
Burn or Write the ISO Image
Now, you are required to write or burn the image of ISO to your disk. For that, you can use Etcher. Thereafter, you can do the following:
- Launch “Etcher”.
- Click on the “Select Image”.
- Locate the “Ubuntu ISO” you installed before.
- Click on the “Select Drive” option in order to pick your USB drive.
- Click on the “Flash” button.
Once you are done following these steps, you can wait for it to burn the image. Thereafter, you are ready to prepare the boot drive. Continue reading to know more.
Step 4: Prepare the Boot Drive
Mac usually doesn’t have a boot menu that can be accessed easily. To deal with this, you need to install your own bootloader. Here, we are using rEFInd as a bootloader for macOS and Ubuntu.
- Download and install rEFInd and unzip the file.
- Find and drag this “refind-installer” on to the Terminal. Doing so, the installer script will run.
- Now, reboot the Mac PC. This helps you to know if you can see rEFInd in the boot menu options.
Note: In case you don’t see rEFInd in the boot menu then you can perform troubleshooting tips available on rEFInd’s website.
Resize the Boot Partition
Mac computers have one hard drive. If you are installing Ubuntu alongside macOS, you need to create an Ubuntu partition on the boot drive. If you wish to dual boot using the same hard drive then you can create an Ubuntu partition with the Disk Utility.
- In the “Disk Utility”, choose the boot disk from the left sidebar.
- Click on the “Partition” option located on the top menu bar.
- Click on the (+) icon in order to add a new partition.
- In the “Partition Information”, select the format as “MS-DOS (FAT). Also, cut down the disk storage.
When you are done resizing the boot partition, you can then initiate the Ubuntu installation on the Mac system.
Step 5: Proceed with Ubuntu Installation
Now, you can finally install Ubuntu on Mac. All you have to do is to reboot the Mac computer. Then, in the rEFInd menu, you can choose the Ubuntu installer.
- Run the “Ubuntu Installer”.
- Select the “Something else” option when you see the “installation type” screen.
- Pick your Ubuntu partition you created earlier. Then, click the (-) icon to delete and return it with some free space.
- Next to this, free space should be selected, and click (+) icon to make a new partition.
- Here, set the partition size as 4000 MB.
- In the “Use as” field, add “Swap”. This will become a swap partition.
- Now again, the free space should be selected when you make a new partition with the remaining space.
- In the use as” field, set it to “Ext4 journaling file system”.
- The “Mount point” should be set to “/”.
- Click “OK”.
- Select the partition (that you created with Mount point “/”) under the “Device for bootloader installation”.
Thereafter, you can complete the installer process and create your user account, and boot in the operating system.
Caution: Once you are into Ubuntu, make sure you don’t restart your computer. If you do so, the Mac will automatically start in the Ubuntu partition. This is why we used rEFInd so that we can select the operating system when you boot.
